Specification of Letters Patent.

Application filed May 19, 1913. Seria1 No.-768,406.

To all whom it may concern:

Be it known that 1, WILLIAM H. HUNT, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Dumping-Wagons, ofwhich the following isaspecification, such as will enable those skilledin the art to which it appertains to make and use the same.

This invention relates to delivery wagons or trucks, and the objectthereof is to provide improved means for raising the front end of thebed or body of a vehicle of this class into an elevated position tofacilitate the discharge of the contents therefromya further objectbeing to provide an apparatus of the class specified by means of whichthe front end of the bed or body may be raised to the highest possibleangle, with reference to the truck frame, consistent with safety so asto produce a complete and quickdischarge of the contents of said bed orbody, a still further object being to provide the bed or body of avehicle of the class specified with a hinge tail gate and means automatically operated. for opening said gate at the desired time and forlocking said gate when the bed or'body returns to its normal position onthe truck frame; and with these and other objects in view the inventionconsists in a mechanism of the class specified constructed and operatingas hereinafter described.

The invention is fully disclosed in the following specification of whichthe accompanying drawings form apart, in which the separate parts of myinvention are designated by suitable reference characters in each of theviews, and in which Figure 1 is a side view of a power driven vehicle ofthe class specified provided with my improvement and showing the frontend or body raised as in the operation of discharging the contentsthereof;Fig, 2 a similar view but showing a modification of the hoistingapparatus, and showing means whereby the bed or body is given a backwardmovement in the operation of.

raising the front end thereof,;Fig. 3 is a view similar to Figs. 1 and 2but showing another modification in the means for raising the front endof the bed or body ;Fig. 4 a partial section on the line 4-4: of Fig.

1'-,Fig. 5 a partial section on the line 5-5 I of Fig. 1 ;-Fig. 6 a rearview of the chassis of the frame and the supplemental truck frame shownin Fig. 2, and showing the bed or body in its normal position and withparts omitted.

The invention described and claimed herein is an improvement on thatdescribed and claimed inan application for Letters Patent of the UnitedStates filed by me September 11, 1912, Serial No. 719,697, and in theaccompanying drawingslhave'shown a power driven vehicle of the classusually employed in the art to which this invention relates, and saidvehicle is provided with the usual chassis frame a, a front axle a arear axle a and front and rear wheels of and a and-in the practice of myinvention as shown in Fig. 1, I provide a supplemental truck framemounted on the chas sis frame and comprising central parallel members 6which correspond with the side bars'of the chassis frame and outside ofwhich are other parallel side bars b which terminate forwardly of andabove the rear wheels a as shown at b, so that the bed or body a of thevehicle will always clear the rear wheels 0?, and. in the constructionshown, the bed or body 0 is longer than the chassis frame andsupplemental truck frame, and the object of using or employing asupplemental truck frame is to elevate the bed or body which overhangsthe rear wheels Patented Sept. v, 1915.

in the usual manner so that in the operation b which is clearly shown inFig. l in full lines and indicated in dotted lines in Fig. 3, and said.cross bar is provided with raised end blocks 6 on which the bed or bodynormally rests and on which said bed or body moves on a pivot when thefront end thereof is raised.

The bed or body is hinged at d to the supplemental truck frame by meansof a pintle rod d mounted transversely of'the supplemental truck frameabove the transverse bar 6 and hinged plates (5 connected with thesupplemental truck frame, and corresponding hinge plates at connectedwith the bottom of the bed or body through which said pintle rod passes,and said pintle rod is arranged between the blocks 6 The winding andhoisting mechanismwhich I employ involves the usual transverse Windingshaft e and crank shaft 6 geared in connection, as shown, and the crankshaft 6 is provided with the usual crank 6. These mental truck frame,two of which are employed, and which correspond in position with theside bars of the chassis frame a, are placed inclined. tracks 6 whichextend from the front end of the supplemental .truck frame forwardly andupwardly, ap-

proximately to the middle thereof, and on these tracks are mounted atransverse shaft 6 having end rollers e which bear on said tracks orways, this construction being also similar to that in the applicationhereinbefore referred to, and. common in other apparatus of this class,and mounted on the shaft 6 inwardly of the side bars b of thesupplemental frame, and inwardly of the rollers e is a pair oftelescopic arms f only one of which is shown, and another pair of arms 9are also mounted on said shaft and only one of which is shown, and theconnection of the arms f and g with the shaft 6 is a pivot connectionthe same as in the application hereinbefore referred to, and theconnection of said arms with the bed or body is shown in Figs. 1, 4, and5, and is of the following construction. Secured to the bottom of thebed or body between the bottom side .rails thereof is a pair oflongitudinal cleats h, but one of which is shown, and whichmay extendthe full length of the bed or body, or which may be of any desiredlength, and secured to said cleats by means of bolts 71. are side plateshwhich extend below said cleats and which are provided with longitudinalslots 11., and the arms 9 are provided with forked heads 9 through whichare passed pins 9 which pass through the slots b and said pins 9 arefreely movable longitudinally of said slots.

The arms I are provided with heads f having side ears 7 and a centralear f", and the central ear f is longer than the side ears and enters acorresponding slot or recess h in the cleats h and the object-of whichis to brace the arms or the connection thereof with the bed or bodyagainst lateral movement in the operation of raising said bed or body.The head 1 is connected with the side plates Ir. by a pin i passedthrough said side plates and through the ears .7 and f of said arms, andit will be observed that the connection of the arms f of the bed or bodyis forwardly of the connection with said bed or body of the arms 9.

The arms I are telescopic arms which may be made in any desired manner,but which,

with initial lift devices or apparatus involving link members i arrangedin pairs and pivoted inwardly of the bottom side rails of said bed orbody and preferably to and inwardly of the cleats h and with which areconnected telescopic thrust rods 21 which are pivoted inwardly of thebars 6 of the supplemental truck frame, as indicated at i, and theconnections of the links 5 and telescopic thrust rods 11 at i are hingedconnections, and connected therewith are link bars 2' also arranged inpairs, and said link bars are connected with the pins g with which theheads 9 of the arms g are connected, as clearly shown in Figs. 1 and 5.i

The bed or body 0 is provided with a tail gate j having a loose hangingconnection with said bed or body at j, and pivoted to the bottom siderails of the bed or body, adjacent to the rear end thereof, as shown at3' are lever arms j with the forward ends of which are connected links iwhich are pivoted below the bottoms of said side rails, as shown at j,to the blocks 1), and the rear ends of the lever arms 3'' are providedwith upwardly directed cam noses j inwardly of which are recesses jadapted to receive pins j on the ends of the tail gate j.

It will be understood that, in practice, chains or similar devices areconnected with the transverse shaft (2 and with the winding shaft 6 inthe usual manner, said chains being shown in Fig. 3. It will also beobserved that the transverse shaft 0 with which the arms f and 7 areconnected, in the form of construction shown in Fig. 1, is forward ofthe transverse center of the bed or body and forward of the windingshaft e, and said shaft is shown in its normal position in dotted linesin Fig. 1. The top walls In the normal position of the parts, the

arms 1 and 9 lie fiat or approximately so in the supplemental truckframe, and the separate parts of the arms f are telescoped together, andthe upper ends of the parts which are connected with the shaft e bear onthe heads of the parts which are connected with the bedor body, as shownat f in weenie Fig. 4, while the lower ends of the parts of said armsthat are connected with the bed or body bear on the shaft 6 The objectof making the arms f telescopic is to be able to obtain a short liftinglevera when the bed or body is in its normal pos sion, or in otherwords, provide a short lift under the Road, and by means of i a quickermore effective operaa of said arms i irovided, and this also v.les meanswhereby the bed or body oe raised to a mu h angle or ation than nootherwise possisaid arms aeration the pins slots a and is movement, linkbars acirhaidly the pivotal or hinged ts of the links 2', and thetelescopic as 21 being in their fully telescoped posi- 11 take thethrust of this pull and the tendency is for the. links 2' to raise thefront end of the bed or body, or help toraise it, and this tendencycontinues until the front enl of the bed or body, reaches a height at wh one part of the telescopic rodsi moves outwardly with reference to theother parts of'said rods.

it be borne in mind that the initial lifting devices i, i and 2' are notan absolutely essential. element in this construction and may or may notbe employed.

the chief difference between the construction shown. in Figs. 2 and 6and that shown in Figs. 1, f and 5 is in the provision of means wherebythe bed or body may be given a horizontal backward movement in theoperation of raising said bed or body, whereby a greater overhang ofsaid bed or body is produced in the operation of dumping the contentsthereof, and whereby the weight of the bed or body with its load isdistributed more evenly over the chassis and on both axles of thevehicle, in the normal position of said bed or body, than is possiblewith the construction shown in Figs. 1, 4L and 5, a further object ofthe construction shown in Figs. 2 and 6 being to provide means wherebythe center of gravity of the bed or body and its load may be movedbackwardly at the beginning of the operation of elevating or raising thefront end thereof so as to reduce the power necessary to raise saidfront end of the bed or body with its load.

The above objects are obtained by providing in the supplemental truckframe, or at the rear end thereof, supplemental truck frame members inwhich are connected directly with the rear end of the chassis frame,

may o-e opei a.

' the tele employed the as in i copic arms f are of sl htly acrentconstruction, and the initial hitting mechanism consisting of the partsi, i and t is omitted, and the tracks or ways are extended forwardlybeneath the seat body of the chassis, and in this form of construction,a chain or other flexible device at is connected with the front the bedor hotly and with a roller shaft m mounted in or over the front endportion of the supplemental truck frame and by means of which the bed orbody may be drawn forward into its normal position, as shown in dottedlines in Fig. 2. v

The construction shown in Fig. 3 is the same as that shown in Fig. 1except that supplemental inclined tracks or ways n are employedrearwardly of the inclined tracks or ways 6 and which extend downwardlyand backwardly between, or inwardly of the rear end portions of the siderails of the chassis frame, and the arms 9' are connected with anindependent shaft 0 provided with rollers o movable on the tracks orways it,

and two sets of winding chains p are employed, both of which areconnected with the main winding shaft 0. in this construction the sametail gate mechanism is employed, as in Fig. 1, and in the operation ofthe winding mechanism, the pins g of the arms 9 are normally in the rearends of the slots h in the plates 72, and move forwardly in said slotswhen the arms 7 are raising the bedor body and its load through itsinitial movement, and when thepins g reach the forward ends of the slotsk the arms 9 take the load, and the telescopic arms f begin theirmovement.
